Larian Studios Forums Divinity 2 - Ego Draconis (English) Divinity 2 - Ego Draconis [Spoilers] Few questions

In Ygerna's memory, I(Or we) killed the Divine and Zandalar. All I know is Divine was captured in the Hall of Echoes, and the player also, but how about Zandalar? The ending make me a little bit confuse...

And now the last Dragon Knight is trap in a different dimension with Lucian...
Is it really our character is the last dragon knight?

And can anyone tell me the weapons below are they appeared in Divine Divinity before? I didn't played the first episode so I don't know the story behind...

Sword of Lord Arben
A legendary dragon slayer's sword I gave to Tilian... (Crying)
Bow of Tibernus
Who is Tibernus actually? All I just know is there has a camp called "Camp Tibernus".
Myrthos
A well-crafted sword that Hermosa's father made, why its name don't appear in Deep red color, it should be a unique item...

Are there any other famous weapon?

Zandalor should still be in Rivellon. The Divine One was already traped in the Hall when you freed Ygerna.
I guess we were the last dragon knights, at least nothing show me the opposite. Even the Patriach thought so.

None of them was in Sword of Lies, as far as I remember. They shouldn't, at least; Arben was a dragon slayer (so he got famous after DD) and Tibernus was a famous guard in the Broken Valley (or the Orobas Fjord? I admit I don't remember, but you never visit these places in the first game). Mythos could have been, but I guess he wasn't there; he got his name from a forum member.
